ABSTRACT
Pre-stenting remains a subject of debate, and its influence on FANS assisted ureteroscopy is unclear. The global collaborative group aims to address the pre-stenting FANS-assisted ureterorenoscopy (URS). This prospective multicentre study assesses outcomes 394 patients undergoing for renal stones. Patients were stratified into non-pre-stented (group 1, n = 163) pre-stented 2, 231). Data demographics, stone characteristics, operative parameters, postoperative 30-day analysed. Statistical analyses, including multivariate regression, performed stone-free rates (SFR) complications. SFR was defined by bone window non-contrast computed tomography (CT). Pre-stented had higher prevalence positive urine culture treated with preoperative antibiotics (23.8% vs 12.3%, p 0.006). Larger volumes noted (1,306 mm3 1,200 mm3, 0.027) in 1. Postoperative complications minor. Sepsis not reported either group. Group 1 incidence low-grade Traxer grade ureteric injuries (4.3% 0.4%, 0.021). resulted high overall SFRs 97.5% 97.0% groups 2. Multivariate analysis showed no statistical difference between (63.2% 53.2%, 0.063). Only thulium fibre laser (TFL) volume significant predictors residual fragments (RF). mandatory irrespective location volume. use TFL significantly influenced SFR, while itself proved highly effective achieving SFR.
